问题描述



guys any way to put a fadeInImage as a background of a cicrle avatar? i'm trying but i get this compiler error


The argument type 'FadeInImage' can't be assigned to the parameter type 'ImageProvider<Object>?'



this is my circle avatar


child: Obx(() {
                    return CircleAvatar(
                      backgroundColor: Colors.grey,
                      backgroundImage: NetworkImage(
                        controller.urlImagem.value.toString(),
                      ),
                      maxRadius: 100,
                    );
                  }),



I want to put this code but this error appears to me at the top


child: Obx(() {
                    return CircleAvatar(
                      backgroundColor: Colors.grey,
                      
                      backgroundImage: controller.urlImagem.value.isNotEmpty ? FadeInImage.memoryNetwork(placeholder: kTransparentImage, image: controller.urlImagem.value) : null,
                      maxRadius: 100,
                    );
                  }),
                ),










Had the same question since the Flutter example didn't mention anything else about it. The solution came from the transparent_image GitHub repo, which is to wrap kTransparentImage in a MemoryImage:


MemoryImage(kTransparentImage);



From the documentation MemoryImage 'Creates an object that decodes a Uint8List buffer as an image.'


标签： flutterdart


解决方案









有同样的问题，因为 Flutter 示例没有提及任何其他内容。解决方案来自t ​​ransparent_image GitHub repo，它包含kTransparentImage在一个MemoryImage：


MemoryImage(kTransparentImage);



从文档MemoryImage“创建一个将 Uint8List 缓冲区解码为图像的对象。”
